・With the ban on Christianity enforced in 1614, the Shogunate strictly cracked down on Christians. Many Christians in the Sotome area continued to practice their faith in hiding.
・Hidden Christians in the Kurosaki area congregated in secret upon the hill of Karematsu to carry on the tradition of “Oratio” (prayer chants).
・At the beginning of the Meiji Era, Christians in this area built a shrine here dedicated to St. John, who was the teacher of the Japanese religious instructor, Bastian.
・Many gravestones still remain today near the shrine, placed upside down in the usual style, thus rendering the epitaphs unviewable.
